Frequently Asked Questions - SOOGM-19L CRUX

Which vehicles does the CRUX SOOGM-19L interface hub support?

The SOOGM-19L is designed for General Motors vehicles with a 19-pin radio connector, typically from model years 2006 to 2013, including Chevrolet, GMC, Buick, and Cadillac models. Always verify your vehicle's connector type before purchase.

Is programming required for installation?

No, the SOOGM-19L is plug-and-play. It requires no programming or external modules. Simply connect the harness between the factory wiring and your aftermarket radio.

Will this interface retain factory chimes and OnStar?

Yes, the SOOGM-19L retains factory chimes, OnStar, and other audio alerts. It also maintains the original steering wheel controls and Bose amplifier integration.

Does it support steering wheel control adaptation?

Yes, the interface preserves factory steering wheel controls. However, some aftermarket radios may require an additional adapter (e.g., ASWC-1) for full functionality. Check your radio's compatibility.

What is the power consumption of the SOOGM-19L?

The interface draws minimal power directly from the vehicle's 12V system, typically less than 0.5 amps. It does not require a separate power source.

Can I install this hub myself?

Yes, installation is straightforward. Disconnect the battery, remove the factory radio, connect the SOOGM-19L harness between the vehicle harness and the aftermarket radio, then secure all connections. Basic wiring knowledge is recommended.

What type of aftermarket radios are compatible?

The SOOGM-19L works with most aftermarket single-DIN and double-DIN radios that have standard ISO connectors. It supports both analog and digital radios.

Does the interface retain the factory backup camera?

If your vehicle has a factory backup camera, the SOOGM-19L can retain it. However, you may need a separate adapter for the video signal depending on your aftermarket radio.

What should I do if the interface does not work after installation?

First, check all wiring connections and ensure the harness is fully seated. Verify that the vehicle's battery is connected. If the problem persists, consult the installation guide or contact CRUX support. Common issues include incorrect vehicle wiring or faulty aftermarket radio settings.

Where can I find the installation guide for the SOOGM-19L?

The installation guide is included in the package. You can also download a PDF version from the CRUX website or from notice-facile.com. The guide provides step-by-step instructions and wiring diagrams.

AUDIO CONNECTION:

Plug in the 8-pin Molex connector of the SOOGM-19L harness to the Black, NON BOSE, port of the module.

BOSE AMPLIFIER BYPASS:

For vehicles equipped with a factory Bose amplifier, extend the speaker wires of the SOOGM-19L harness and connect to the Bose amplifier output wires. Locate the Bose amplifier to find out how much speaker wires is necessary. The Bose amplifier is located as follows: (NOTE: Bose amplifiers are commonly found in the locations listed below but the manufacturer can mount it elsewhere. Installer should verify the location before installation.)

Trucks = Center of the rear wall / SUVs = Center console or in the cargo space / Sedans = Rear deck or Trunk area

CHIME VOLUME ADJUSTMENT:

The SOOGM-19L has a potentiometer to adjust the chime volume. It is set at half way by default. To adjust the volume, simply use a suitable screw driver and turn the potentiometer clockwise to increase the volume and counter-clockwise to decrease the volume.

ONSTAR VOLUME ADJUSTMENT:

To adjust the OnStar volume, turn on OnStar and adjust the volume using the SWC volume adjustment. There are 4 steps of volume control. Once it is set, the SOOGM-19L will memorize this level.

INSTALLATION INSTRUCTIONS:

1. Connect the aftermarket radio's power/speaker harness to the SOOGM-19L T-Harness using the Installation Diagram on page 1. Use good quality crimp caps or butt splice for a secure connection. Solder and heat shrinking the connections is highly recommended.

1. Use the supplied antenna adapter to plug between the OE antenna connector and aftermarket radio antenna port.

2. Remove plastic trim under the steering wheel column and locate a GREEN/BLACK wire in the bundle. Tap the GREEN/BLACK from the SWC Cable. We recommend soldering the wires together for a reliable connection.

1. Use a dash kit (not included) for a clean install. Test the radio for functionality. Test the chime and Retained Accessory Power (RAP) functions. Reverse the process to install the new aftermarket radio.

OEM CAMERA RETENTION:

The SOOGM-19L is prewired with an RCA connector to retain the OEM camera on vehicles with a IO3 system. To retain the OEM camera on IO4, IO5 and IO6 systems, you will need connect an RCA cable to the 12-pin connector on the HMI module found either by the passenger kick panel or behind the glove box. Connect the RCA as follows:

HMI Connector

PIN 5 = Gray/Yellow to RCA positive

PIN 6 = White/Blue to RCA shield

We recommend soldering and heat shrinking these wires for a secure connection.

3.5MM SWC CABLE

Plug in the 3.5MM to 4-Pin SWC cable to the SWC module.

NOTE: Cap or Insulate the 3.5mm plug and Blue/Yellow wire if not being used.

For aftermarket radios that have wires for SWC connections, cut off the 3.5mm plug on the Crux SWC Cable (option B) and connect the SWC wires as follows:

RED to SWC Key 1 WHITE to SWC Key 2 SHIELD to SWC Ground

Note that there are some radios that only have SWC1 and SWC2, in this case “shield” does not need to be connected.
